Re: iPad version
There's Caylus on the ipad.
I never played Caylus, but LoWD was often called a Caylus clone.
You might want to check it out.
Anyhow, if WotC make an ipad version of LoWD, Id get it on the spot.
I hated Caylus, but I love Lords of WaterDeep.
I doubt to see that one on the iPad anytime soon, for the reasons mentionned, Hasbro doesn't do that much, at least with success.
